Abstract :
We proposed and demonstrated a novel time domain spectral phase encoding/decoding scheme by time domain stretching and high speed phase modulating short optical pulses. 16 chips, 40 GHz/chip optical codes have been generated and recognized successfully using long chirped fibre Bragg grating (LCFBG) as dispersive components, respectively. Transmission experiments have been carried out successfully with 2.5 Gbps over up to 50 km SMF.
